How can you optimize the size of a deployment package for an AWS Lambda function?
- Enable verbose logging, Include comprehensive documentation, Add encryption keys
- Increase dependencies, Use a larger runtime, Include all available libraries
- Minimize dependencies, Use a smaller runtime, Remove unused code and libraries
- Minimize memory allocation, Include large data files, Add debugging information
To optimize the size of a deployment package for an AWS Lambda function, minimize dependencies, use a smaller runtime, and remove unused code and libraries.
What is the role of AWS SAM (Serverless Application Model) in managing deployment packages?
- AWS SAM automates manual deployment processes
- AWS SAM increases the complexity of managing serverless applications
- AWS SAM replaces AWS Lambda in managing serverless applications
- AWS SAM simplifies defining and deploying serverless applications
The role of AWS SAM (Serverless Application Model) in managing deployment packages is to simplify defining and deploying serverless applications by providing a declarative way to define resources and configurations.
How does AWS Lambda handle updates to deployment packages?
- Immutable updates
- In-place updates
- Manual updates
- Versioned updates
AWS Lambda supports in-place updates, where the new deployment package replaces the previous one without creating a new version or alias.
What are the considerations for managing versioning of deployment packages in AWS Lambda?
- Cost optimization
- Dependency management
- Rollback strategy
- Security measures
Versioning deployment packages in AWS Lambda requires considering dependencies to ensure compatibility and consistency across versions.
How can you automate the deployment process of AWS Lambda functions and their packages?
- AWS CodePipeline
- AWS Console only
- Email notifications
- Manual uploads
AWS CodePipeline allows you to automate the build, test, and deployment process of AWS Lambda functions and their associated deployment packages.
When creating a deployment package for AWS Lambda, it's essential to include the __________ file to specify the function's entry point.
- config
- handler
- index
- package
The handler file is crucial in an AWS Lambda deployment package as it specifies the entry point for the function.
AWS Lambda deployment packages should adhere to size limits to ensure __________ performance and reduce cold start times.
- dynamic
- maximal
- minimal
- optimal
Adhering to size limits ensures optimal performance by reducing the time it takes to load and execute the function, especially during cold starts.
The __________ feature of AWS Lambda allows you to reuse common code across multiple functions, reducing duplication in deployment packages.
- Lambda Events
- Lambda Functions
- Lambda Layers
- Lambda Triggers
Lambda Layers enable you to centrally manage common code or dependencies across multiple Lambda functions, reducing the size of deployment packages and minimizing duplication.
In AWS Lambda, you can leverage __________ to create layers containing shared libraries, custom runtimes, or other dependencies.
- AWS CLI (Command Line Interface)
- AWS Lambda Console
- AWS SAM (Serverless Application Model)
- AWS SDK (Software Development Kit)
AWS SAM (Serverless Application Model)
Scenario: You have a large AWS Lambda function with several external dependencies. What strategies would you employ to optimize the deployment package size and improve performance?
- Increase memory allocation
- Split the function into smaller functions
- Use Lambda Layers
- Utilize native AWS services
Using Lambda Layers allows you to package and manage libraries separately from your function code, reducing the size of the deployment package and improving performance by enabling code reuse.
